Embodiment Construction
[0017] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0018] like Figure 1 to Figure 3 The shown inspection well climbing ladder of the present invention consists of a round steel ladder body, and the ladder body includes a pedal rod 1, two angled legs 2 and two connecting rods 3. The corner leg 2 includes a corner section embedded in the wall and an exposed straight section. Threads can be set on the corner section to enhance the bonding force embedded in the wall, and enhance the pressure resistance and impact resistance when climbing the ladder. The straight section is connected to the rod end of the pedal rod 1 through the connecting rod 3. The pedal rod 1 and the curved section are placed on both sides of the straight section. In order to maintain a balanced force and withstand long-term use, the connecting rod 3 can be selected Connect perpendicular to the straight segment. The pedal surface of t...

The invention discloses an inspection well crawling ladder. The inspection well crawling ladder comprises a crawling ladder main body made of round steel; the crawling ladder main body comprises a foot rest lever, two bended supporting feet, and two connecting rods; each bended supporting foot comprises a bended segment embedded into walls and an exposed straight segment; each straight segment is connected with one end of the foot rest lever via a corresponding connecting rod; the foot rest lever and a bended segment are arranged on the two sides of a corresponding straight segment respectively; a foot rest surface of the foot rest lever is a concave surface with inclination angles ranging from 3 to 5 DEG C from the middle part to the two end parts; the foot rest lever, the connecting rods, and the straight segments are all coated with skid-resistant layers made of corrosion-resistant plastic. Structure optimization is adopted, so that stability and gravity center balance can be maintained easily when the inspection well crawling ladder is used by servicemen, slipping is not easily caused, and powerful guarantee is provided for safe repair operation.
Description
technical field [0001] The invention relates to the technical field of communication engineering, in particular to a climbing ladder for inspection wells. Background technique [0002] In recent years, with the rapid development of science and technology, the communication industry has developed rapidly, and a large number of communication cable laying and maintenance projects have emerged. A large number of communication cables in the city are laid in underground inspection shafts, and engineering maintenance personnel use ladders to enter and exit underground communication inspection shafts. However, it is not convenient to carry a ladder for maintenance work, so a fixed climbing ladder is arranged on the side wall inside the communication inspection shaft, but the pedal position in the ladder structure of the prior art is linear, and when the maintenance personnel steps on it It is easy to be unstable, and when it is serious, it will fall into the well and cause unnecess...
